Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wide television receiver (international patent classification H04N 5/44) for displaying an aspect ratio of a normal 4: 3 image on a 16: 9 wide aspect display screen.

[0002]

2. Description of the Related Art Conventionally, in a 16: 9 wide television receiver, when a normal 4: 3 image is displayed in a wide aspect screen, the manufacturer side automatically displays it as shown in Japanese Patent Laid-Open No. 143419/1995. In the aspect conversion mode (hereinafter, referred to as zoom mode) in which the range to be enlarged and displayed on the 4: 3 screen is set in advance.

When a video source as shown in FIG. 5 is displayed in a wide aspect ratio, the subtitle supermarket outside the display area is removed from the display screen, so that it can be viewed in the 4: 3 normal mode or only in the horizontal direction of FIG. I am watching in the expanded full mode.

As shown in FIG. 6, in the case of a video source in which the subtitle superimpositions exist in the upper and lower black bands of the screen, the subtitle superposition portion is extracted and moved to the video area.

[0005]

In the conventional wide television receiver, when a 4: 3 video source is aspect-converted to fill a 16: 9 wide display screen, the vertical center, which is the display range set by the manufacturer, is set. Although the part is displayed enlarged, the upper and lower parts of the image information are cut in that case, which causes inconvenience in the case of a video source with useful information such as subtitles and text information in the upper and lower parts of the screen. It was

In view of such problems, an object of the present invention is to allow a user to freely set a display range so that image information can be effectively taken in according to various image sources and enlarged and displayed in a wide aspect. To do. In addition, it is possible to specify only a part of the image according to the taste of each person, and to enlarge that part of the display screen to enjoy the image.

[0007]

In order to solve the above problems, the present invention is an image processing circuit for extracting a display screen of a 16: 9 wide television and an enlarged display range of a transmitted video signal. And a wide television display screen having an aspect conversion circuit for converting the aspect display, an aspect conversion button and a display range setting button provided on the remote controller transmitter or the receiver body, and the aspect conversion button and the display range setting An analysis means for decoding the instruction content by the button is provided, the aspect conversion button is used to enter the display range setting mode of the 4: 3 screen, and the display range setting button is used to specify the expansion range on the 4: 3 screen. The present invention provides a wide television receiver characterized by enlarging and displaying on 9 display screens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention comprises a display screen of a 16: 9 wide television, an image processing circuit for extracting an enlarged display range of a transmitted video signal, and an aspect display. Decodes the aspect conversion button and display range setting button provided on the remote control transmitter or the main body of the receiver and the instruction content by the conversion button and display range setting button on the display screen of the wide television equipped with the aspect conversion circuit for conversion. An analyzing means is provided to enter the display range setting mode of the 4: 3 screen by the aspect conversion button, and the expansion range on the 4: 3 screen is designated by the display range setting button to expand the screen to the 16: 9 display screen. Is displayed.

The present invention will be described below with reference to FIGS. 1 to 4. (Embodiment 1) FIG. 1 shows a block diagram of a wide television receiver of the present invention. In FIG. 1, when the aspect conversion button is pressed in the normal mode of 4: 3 by the remote control transmitter 3, the microcomputer 5 is passed through the remote control receiving circuit 4.
To output a range designation cursor for designating the display range on the 4: 3 screen as shown in FIG. Move the range specification cursor (specified size is fixed, only position is changed) to the video part you want to display with the display range setting button of the remote control transmitter, and when you decide, analyze the specified image range position with the microcomputer, image Processing circuit 1
Then, the designated image range is extracted, input to the aspect conversion circuit 2, the aspect is converted to 16: 9 display by the same process as the conventional zoom conversion, and the image is supplied to the video display device 6.

(Embodiment 2) FIG. 3 illustrates the operation of Embodiment 2 of the present invention. In a 2-split display screen of a wide television receiver, a 4: 3 normal display is displayed on the left screen. Then, both the designated range and the screen position are changed using the range designation cursor, the image portion to be enlarged and displayed is designated, the above-mentioned processing is performed, and the enlarged display is performed on the right screen.

(Third Embodiment) FIG. 4 is a diagram for explaining the operation of the third embodiment of the present invention. In a parent-child screen display system of a wide television receiver, a child screen is a normal 4: 3 screen. As a display, the display range is set on the child screen using the above-mentioned range designation cursor (the designated size is fixed, only the position is changed), and enlarged display is performed on the parent screen.

[0012]

As described above, according to claim 1 of the present invention, it is possible to perform zoom display on a wide aspect screen without missing a subtitle super in video sources with various types of subtitles. With respect to the movement of the subtitles existing in the black bands at the top and bottom of the screen, the complicated process of extracting subtitles and rearranging the subtitles on the effective image as in the past is not necessary.

According to the second aspect of the present invention, the user can freely set the position and size of the range to be displayed in the 4: 3 video, so that the video information can be effective according to the taste of each person. There is an effect that can be utilized.

According to the third aspect of the present invention, the parent-child screen display is used so that the range can always be designated on the child screen, so that the change of the video source can be immediately followed and the video information is missed. There is an effect that you can get without.
